Some Lady Copied Down my License Plate Number?

So. I had a minor accident where someguy and I backed up into eachother. It was too minor to report, and there was no damage. But I left my car in the way of a two way street. There was still enough space for anyone to p through. I was on a school parking lot by the way. She was yelling at me to move, and I told her to please wait while i was talking to the guy. So she got off Wrote down my License Plate Number, and Sped off. Am I in trouble????
